The attempted assassination of Iraqi Prime Minister Mustafa al-Kadhimi at his Baghdad home Sunday represents a grave escalation in that strife-torn country. The political authorities' response may determine whether Iraq has a chance to emerge from endless crisis or is set on a path of Lebanonization—de facto rule by armed militias in the service of a foreign state.
No group has claimed responsibility for the three drones launched at Mr. Kadhimi's residence in the Green Zone, the area where government offices are located in Baghdad. But the affiliation of the perpetrators is not in doubt. Only Iran-supported Shiite militias have the means, motivation and ability to mount an armed drone attack of this type.
